vano
/ˈbano/ · B1 · adj
span
🦚 vano = Latin vanus, empty: vain, vanish, and the gap a bridge spans
Every sense is about emptiness: a vain person is full of nothing, a vain effort comes to nothing, and a vano is the empty gap between bridge piers or in a door frame. Same root as English vanish. Careful: it sounds just like baño (bathroom).
